Right now, I play no gambits, and am about 1700 FIDE. Someone said to me that at my level, tactics were the most important thing, and to really improve tactics, I should play non-dubious gambits like the Scotch or the Evans to get into tactically rich positions. Right now I’ve been playing mainlines more so, like Ruy Lopez, Open Sicilian, etc.

Is this guy‘s advice solid and should I start playing some gambits, even in classical otb? If so, until what rating does this advice work until I should switch to more solid openings?
