Kd8 $3 {And the attack after: Qb4 Nxb5 Rf1 Also seem crushing. However, it transpires that the second player can hold with a nice sacrificial idea in the line: Rxc3+ Kd1 Rxa3 Rf8+ Kc7 Qc5+ Bc6 Rxg8 All of this forced.

A pity for Tari who could have won thanks to: Re4+ Kc7 Kc8 Qf8+ Rxg4 Rxg4 Nc3 The Q+$146 in the attack quickly win material or mate the black king after: R4xg7 Nxd5+ Kc8 Qc3+ White's idea is understandable in the line: Rf7+ Kc7} 21...
