May-02-06		DAL9000: Why 8... h5 instead of 8... Bxf3 and /then/ ... h5 after the recapture?

Nov-16-13		offramp: Today's puzzle is not too hard. White wants to plsy Qxe5+. So he gets his bishop d3 out of the way, then takes the black knight on d7.

Nov-16-13		paramount: good puzzle but maybe for yesterday... Nice

Nov-16-13		LoveThatJoker: <19. Bxb5!> A) 19...Bc8 20. Bxd7+ Bxd7 21. Qxe5+ B) 19...axb5 20. Rxd7 Qxd7 (20...Kxd7 21. Rd1+ ) 21. Qxe5+ Qe7 22. Qxh8 Qf8 23. Qe5+ is a fine way to continue as after 23...Qe7 24. Qh8+ Qf8, White can decide whether or not he wants to keep Queens on board or whether he wants to simplify into a endgame two pawns up. LTJ

Nov-16-13		morfishine: A good example of why chess is so alluring: Today, two themes combine to give White a decisive edge. First, a clearance theme with 19.Bxb5, then remove the defender of e5 with 20.Rxd7. Interwoven is a piece sac and an exchange sac. All this is done so White can play Qxe5 at some point achieving a winning position. <19.Bxb5> Clearance theme opening the d-file <19...axb5 20.Rxd7> Removes the defender of e5 <20...Kxd7> Forced due to 20...Qxd7? 21.Qxe5+ followed by 22.Qxh8+ <21.Rd1+ Kc6> Best since 21...Kc7 22.Qxc5+ or 21...Ke7? 22.Qxe5+ <22.Rxd8 Rhxd8 23.Qxe5 Rxa2 24.Nd5> *** PM: After reading the posts, I'd agree that concerning the level of difficulty, this POTD is somewhat below a "Saturday level". However, this doesn't detract from the attractiveness of the combination, the richness of the ideas involved, nor the thematic value of the overall forcing sequence. ***

Nov-16-13		gofer: White wants to play Qxe5+ as that will win everything. So sacrificing Be3 and exchanging down Rd1 seems like a fair way to achieve that goal. <19 Bxb5 axb5> <20 Rxd7 ...> Okay white has removed the lone defender of Pe5, but what is black's best defence? 20 ... Qxd7 21 Qxe5+ ... 21 ... Kf8 22 Qxh8+ Ng8 23 Nh7+ Ke7 24 Nf5+ Kd8 25 Rd1 21 ... Kd8 22 Qxh8+ Kc7 (or possibly 22 Rd1 Qxd1+ 23 Kxd1 Kd7 24 Qxc5 ) 23 Qxh6 <20 ... Kxd7> <21 Rd1+ Kc7> <22 Qxc5+ Kb8> (22 ... Bc6 23 Rxd8 Rhxd8 24 Nd5+ ) <23 Rxd8 Rhxd8> <24 Nd5 > ~~~ Hmmm, perhaps a little easy for a Saturday, but I enjoyed working out what happened after <20 ... Rxd7>. There are still a lot of options for black, just they all seem to be bad options... I didn't get the game continuation, but I think black is in a pretty forlorn position...

Nov-16-13		Penguincw: I knew it was 19.Bxb5! Not sure why, but just had a feeling it was right for Sunday.

Nov-16-13		BOSTER: After qame 6 Carlsen vs Anand where computer evaluation 1000.0 !! POTD looks like from another planet.

Nov-16-13		kevin86: white sacs set up a quick win.

Nov-16-13		M.Hassan: "Very difficult" White to play 19.? Equal Opening up the d file can bring opportunities for White: 19.Bxb5 axb5 20.Rxd7 Qxd7 <if...Kxd7 21.Rd1+ Kc7 22.Rxd8 Rhxd8 23.Qxc5+ Bc6 24.Qxe5+ Kb7 and White looses 2R+B and gains Q+N+3p so I think 20...Qxd7 may be better for Black> 21.Qxe5+ Qe7 22.Qxh8+ Qf8 23.Qf6 Rxa2 24.Kb1 Ra6 25.Qe5+ Qe7 26.Qb8+ Qd8 27.Qxb7 Rd7 28.Qxb5+ Kf8 29.Qxc5 White has now a huge advantage of N+3p time to check

Nov-16-13		agb2002: The material is identical. The black king in the center and the defenseless rook on h8 suggest 19.Bxb5 axb5 (19... Bc8 20.Qxe5+) 20.Rxd7 destroying Black's center: A) 20... Kxd7 21.Rd1+ A.1) 21... Kc6 22.Rxd8 Raxd8 (22... Rhxd8 23.Qxe5 Rxa2 24.b4 cxb4 (24... c4 25.Qc5+ Kd7 26.Qxb5+ Kc8 27.Qxc4+, etc.) 25.Nxf7 Nxf7 26.Qe6+, etc.) 23.Qxe5 + - [Q+N+2P vs 2R+B]. A.2) 21... Kc7 22.Qxc5+ Kb8 (22... Bc6 23.Rxd8 followed by 24.Nd5+ looks crushing) 23.Rxd8+ Rxd8 24.Qxe5+ and 25.Qf6 wins more material. A.3) 21... Kc8 22.Rxd8+ Rxd8 (22... Kxd8 23.Qxe5 and 24.Qxc5) 23.Qxc5+ Kb8 (or 23... Kd7 24.Qxb5+) 24.Qxe5+, etc. A.4) 21... Ke7 22.Qxe5+ Kf8 23.Rxd8+ Rxd8 24.Qxh8+, etc. A.5) 21... Ke8 22.Rxd8+ Kxd8 23.Qxe5 looks similar to previous lines. B) 20... Qxd7 21.Qxe5+ B.1) 21... Qe7 22.Qxh8+ Qf8 (22... Kd7 23.Qxh6) 23.Qf6 + - [N+2P vs B] (23... Rxa2 24.Kb1 followed by 25.Qb6, Rd1, etc.) B.2) 21... Kf8 22.Qxh8+ Ng8 23.Nh7+ Ke7 24.Rxg8 wins (24... Rxa2 25.Qf6#). B.3) 21... Kd8 22.Qxh8+ Kc7 23.Qxh6 Rxa2 24.Kb1 + - [2N+P vs B].
