answers!

1. 29. Bg4! is best, as 29...Rxg4 30. e6! Qg7 31. Rf7 Qg8 32. Qe5! is crushing. This variation was spotted by Knights Assistant Manager Matt Herman; in actuality Romanenko played 29. Qc3.

2. 47. b5! works, since 47... Rxb5 48. Rxa2+ Kxa2 49. Nc3+ wins.

3. 24... Bc4 is winning, as moving the rook allows the devastating ...Qxb2

4. 13...Ndxe5! wins a pawn, since 14. fxe5 allows 14... Qh4+. 13... Ncxe5 also wins a pawn, but doesn't free the black queen so nicely.

5. Black's strongest is the amazing 14...Bb7, threatening to threaten ...Bxg2. After 15. fxe5 Nd4 16. Kf2 Nc2, black is winning the exchange.
14... Nd4 is also good, since 15. Bd1 Bb7 16. Kf2 is met with 16...Nc2 17. Bxc2 Ng4.

6. The game finished with 23... Rxe2 24. Nxe2 Qc6!
