DrGridlock: Palciauskas writes in the annotation to white’s move 18 f4, “the only hope for the attack is the advance of the kingside pawn majority. But this doesn't turn out well because I will have a firm control of the square f5.”Fritz sees things differently, evaluating the continuation 18 Qg5 h6, 19 Qxe7 Bxh3, 20 Bg5 Rfe8, 21 Qxc7 Bxg2, 22 Kxg2 Qxg5+, 23 Kh3, Qh5+, 24 Kg3, Qg5+ as a small advantage to White (.16). Fritz sees the game continuation 18 f4 as White’s 16th best move option, shifting the advantage to black (-.50).
Palciauskas gives his move 18 … c5 an (!), but Fritz prefers the continuation Rd8 (-.53) to the game move (-.16). White seems to get into trouble with his move 24 Qa6 (-.66). Fritz prefers white to continue 24 Rb1 (-.31). The acid test of Palciauskas’ line and annotation seems to be whether there is an improvement to the line 24 Rb1 Rd3, 25 c4 Rd4, 26 Qa8+ Kh7, 27 Qa4 Qe6, 28 Rb2 Rxc4, 29 Qd1 h4, 30 Qh5+ Kg8 31 Rd1 which is the position Fritz evaluates as -.31.
Qa4 dug white deeper at move 25 (-1.19), while Fritz preferred white to play a4 at move 25 (-.56). White’s e6 at move 27 is a blunder which brings the game to a quick conclusion (Fritz evaluates the position as -4.06 after e6).
