Position after} 33. Qd6 {Nana threatened to continue with an ugly check on f8 followed by a knight mate on f6. The only way to defend this was to sacrifice my queen on b4. Unfortunately, I understood that at that time. I tried to convince my opponent to forget about my executing a move, by offering the draws ten times in a row. Even Nana's mum, who was watching the action together with my father in the audience at that time, was as caring as a mum can be and made it clear to Nana that a draw was a good decision. My father, who is a grandmaster, was also clearly in favour of this idea. Unlike Nana's worried mum, he concentrated exclusively on the chess and not the health issues at this moment. And of course he realized how bad things were for me. Nana nevertheless remained steadfast and refused. I thought and thought and thought. On the one hand, I knew that I would be checkmated after Qc1+ followed by Qxb2 after e4-e5. On the other hand, I couldn't imagine that my opponent would accept my offer of a draw after any move that resulted in a piece loss. After 20 minutes thinking about the consequences of my next move, I finally decided on the "correct" Qc1+ and was visibly relieved when Nana's stretched out her hand to accept the draw.} Qc1+ {Draw accepted.} (33... Qc1+ 34. Kh2 Qxb2 35. e5 ({or} 35. Qf8+ Kh7 36. e5 {with mate to follow.})) 1/2-1/2
