thomastonk: White's opening didn't work well, but Euwe had difficulties with his queen: 17.. ♕e7, 22.. ♕d7, 23.. ♕b7. Instead b6 would have been a nice square, say in move 16.
The tactics beginning with 26.♗xh6 are very interesting, and the move is quite correct. But Euwe plays f5 and ♘c3, but he should only play one of them. 28.♕e3! is strong, though it looks like White is overloading his queen.
But the next move, 29.♘g5? is weak, and shows that Prins overestimated his chances. Instead 29.♗f4! would have kept the advantage (note that 29.. g6 doesn't work at all). Now Euwe missed a fine blow: 29.. f4! This destroys the coordination of White's forces and frees the Black bishop on h7: 30.gxf4 gxh6 31.♘xe6 ♗f5! with an advantage for Black.
After 31.♘xf4, White has three pawns for the piece, and Black's king is not so safe. Nevertheless, I would slightly prefer Black here.
32.. ♘xa2 is not good. It grabs a pawn, but Black should first attack e2, say 32.. ♕e6. Therafter, he would have had good chances to revive the bishop on h7. Now, Black loses a pawn and his position becomes much worse, and after 40.. Sa7? it collapses.
Definitely a deserved win for Prins.
